In the correctly worked addition problem above, M, N, R, S, T and V are distinct digits. Is R > 3?
(1) M, N and P are positive even integers.
(2) S = 2

Kudos for a correct solution.i think answer is B
I suppose P is also distinct digit
1. M, N and P are positive even integers.
[2,4,6,8]
if R=3 then
M 3
N 3
P 3 +
_ _ 9
now take any value of M,N,P from 2,4,6,8 we will get a 3 digit(distinct) sum
if R = 4
then also for any even value of M,N,P from 2,4,6,8 we will get a 3 digit(distinct) sum.
Not sufficient
(2) S = 2
if R = 3
take any value of M,N,P from 1,2,3,4,5,6,7,8,9 such that there sum gives a 2 digit no with S = 2
this will also get satisfied if R=4
thus not sufficient
(1)+(2)
S=2 and M,N,P from 2,4,6,8
only R>=7 will satisfy the condition that S(2), T, V all distinct.
i.e. take M,N and P as 4,6,8
4 7
6 7
+8 7
2 0 1
